Description

符合于弧形表面的柔性触摸板传感器网格背景1. 技术领域本发明一般涉及组合计算机输入装置,如键盘和触摸板(touchpad). 更具体地说,本发明涉及把键盘的现有部件与一集成结构的触摸板组合起来,用于一个改进的系统把带有触摸板电路的PC板与键盘部件耦合, 本发明还涉及把触摸板的柔性传感器部分和该触摸板的刚性电路部件部分与其他部分組合起来。 BACKGROUND 1. Field of the flexible grid touchpad sensor arcuate surface conforming to the present invention generally relates to a combination of computer input device such as a keyboard and a touch pad (touchpad). More particularly, the present invention relates to a keyboard with a conventional member a touch panel integrated structure in combination, an improved system for the PC board with a keyboard and touchpad circuitry coupling member, the present invention also relates to a rigid portion of the flexible circuit member and a sensor portion of the touch panel with the touch panel other parts together. 2. 背景技术现有技术包括提供具有集成触摸板的计算机输入装置的系统。 2. The prior art includes providing a computer system with an integrated touch panel input device. 例如, 现有技术包括信息室(Kiock)、计算机键盘以及利用触摸板作为输入接口的信息装置。 For example, the prior art includes information chamber (Kiock), a computer keyboard and a touch panel as input means using the interface. 可能最通用的装置是计算机键盘。 Perhaps the most common device is a computer keyboard. 在键盘和触摸板技术领域中公知的是它们能被包括在同一个键盘壳体或机架内。 Keyboard and touchpad technology known in the art is that they can be included in the same housing or a keyboard rack. 例如,图1 显示现有技术的典型的QWERTY键盘10的顶视图,它已把10键数字键盘12移动到更靠近字母键,并把触摸板14放在了它的位置。 For example, FIG. 1 shows a top view of a typical prior art QWERTY keyboard 10, which is 10-key numeric keypad 12 Yiba moved closer to the letter keys, and the touch pad 14 in its position. 图2是由先驱技术构成的另一键盘18,它利用了一种人类工程学设计。 FIG 2 is another keyboard 18 consisting of a pioneer technology, which utilizes an ergonomic design. 键盘18有一个触摸板20放在键盘下方手腕放置的区域。 Keyboard 18 has a touch pad area 20 on the keyboard placed below the wrist. 这一安排使10鍵键盘22仍在键盘18中它的最熟悉的位置。 This arrangement is still in the 10-key pad 22 keyboard 18 in its most familiar position. 不幸的是,由于一些重要的理由,把触摸板放入键盘中并不总是一件简单的任务。 Unfortunately, due to some important reasons, the touch pad into the keyboard is not always an easy task. 例如,显然希望使键盘尽可能地便宜。 For example, it hopes to make cheap keyboard as much as possible. 触摸板也有部件成本,它们还有某些结构上的要求不同于键盘而且往往比键盘的成本更高。 There are also cost touch panel member, as well as they require a certain structure different from the keyboard and often more than the cost of the keyboard. 在解释了典型现有技术的键盘的内部结构之后将讨论这些方面。 After explaining the internal structure of a typical prior art keyboard we will discuss these aspects. 图3说明制造键盘内部结构的一种方法。 3 illustrates a method for producing an internal structure of the keyboard. 在该图中显示了键盘的内部布局,它是使用类似塑料的材料(如聚酯薄膜)做成的几层薄片(sheet) 构成的。 Shows the internal layout of the keyboard in the drawing, it is to use a plastic-like material (e.g., polyester film) made of several layers of sheet (Sheet) configuration. 这些薄片在性质上一般是不导电的。 The sheets in nature generally is not electrically conductive. 第一薄片30有多个导电迹线32分布在上面,是用导电材料如碳墨或银墨画出的。 The first sheet 30 has a plurality of conductive traces 32 located in the top, with a conductive material such as carbon ink or silver ink drawn. 这些导电迹线32 横断的位置是当键盘的键被按下时在第一薄片30上与之接触的位置。 These conductive traces 32 position is a position transverse to the first sheet 30 when the keyboard keys are pressed in contact therewith. 还可使用简单的丝网印刷工艺在聚酯薄膜上分布墨迹线。 It may also be a screen printing process using a simple line in the distribution of ink on a polyester film. 重要的是要理解这一墨迹应用工艺不是特别精确,所以通常用于容限(tolerance)高的过程,如在键盘的导电迹线上使用。 It is important to understand this process is not particularly precise application of the ink, it is usually used for tolerance (Tolerance) high process, such as conductive traces used in the keyboard. 第三聚酯薄片36也有导电迹线38,它们横切键盘键的每个位置,与第一薄片30的导电迹线32相同,但沿着不同的轴线。 A polyester sheet 36 also has a third position of each of the conductive traces 38, which transverse keyboard key, same as the first conductive trace 30 of the sheet 32, but along different axes. 第二或者说中间的聚酯薄片40用于在键未被按下时使第一薄片30 与第三薄片36分开。 The second or intermediate polyester sheet 40 for the first sheet and the third sheet 30 when the key 36 is not pressed apart. 在第二薄片40中做了许多孔42,它们也对应于键盘的键的位置。 In the second sheet 40 made a number of holes 42, which also corresponds to the position of the keyboard keys. 这样,当一个键被按下时,由于在中间薄片或者说第三薄片36中有相应的孔42,使在第一薄片30上的导电迹线32能被按下与第三薄片36上的导电迹线38接触。 Thus, when a key is pressed, since the sheet 36 or in a corresponding hole 42 of the third sheet, the conductive traces on the first sheet 30 and 32 can be pressed on the third sheet 36 in the middle 38 contacts the conductive trace. 这一按使在一个唯一位置的一组导电迹线32、 38压在一起,形成了一个电路径,它由键盘电路感知,从而确定哪个键被按下。 The pressure in the press so that a position of a single set of conductive traces 32, 38 together to form an electrical path, it is perceived as a keyboard circuit, to determine which key is pressed. 键盘电路是至少一个集成电路,它位于与塑料薄片30、 36、 40分离的一块PC板上。 At least one integrated circuit is a keypad, which is located 30, 36, 40 of a separate PC board and a plastic sheet. 已经解释了现有技术的键盘的典型内部结构和搡作,而添加触摸板使结构复杂了,因为触摸板通常要求一个刚性PC板(印刷电路板)作为其传感电路的一部分。 Has been explained in the prior art keyboard and shoving as a typical internal structure, the complex is added to make the structure of the touch panel, since the touch panel usually requires a rigid PC board (printed circuit board) as part of the sensing circuit. 例如, 一个电容敏感触摸板通常要求一个PC板用作为一个表面,在其上放置传感电极。 For example, a capacitance sensitive touchpad typically require a PC board is used as a surface, the sensing electrodes disposed thereon. 使用PC板的理由是这些电极的相对位置通常要求很准确,因为现有技术的触摸板传感电路没有大的制造误差容限。 The reason for using such PC board is a relative position of the electrode typically requires very accurate, since the prior art touchpad sensing circuit is not large manufacturing error tolerance. 对制造不规则性的这一容限通常是触摸板电路本身的函数。 The manufacturing tolerances of the irregularities is usually a function of the touchpad circuitry itself. 触摸板电路固有地对电噪声、电极间距以及其他因素敏感,这些因素限制准确检测和确定触摸板表面上指示对象位置的能力。 Electrical touchpad circuitry is inherently noise sensitive electrode spacing and other factors, these factors limit the ability to accurately detect and determine a position indication object on the touchpad surface. 例如,以很精确的图案或网格布置X和Y导电迹线。 For example, in a very precise patterns X and Y grid arrangement or conductive traces. 本发明人已知的所有触摸板电路的误差容限(动态范围)是这样的,即在没有精确的网格布置的情况下触摸板将不^作用,而只有使用PC板才能一致性地实现这种精确的网格布置。 All error margin touchpad circuitry of the present invention is known (dynamic range) is such that the touchpad ^ will not function without a precise grid arrangement of the case, and only the PC board can be used to achieve consistency this precise grid arrangement. 换言之,现有技术的触摸板通常是如此敏感, 以致于如果要把触摸板包括在一个键盘壳体内的话,就必须在键盘壳体内包括一个用于触摸板传感电极网格的PC板。 In other words, the prior art touch panel is usually so sensitive, so that if we want to touch panel includes a PC board in case of a keyboard housing, the housing must be within the keyboard comprises a touchpad sensing a grid electrode. 在检验包括触摸板的现有技术键盘的结构时发现,塑料薄片通常被移去或使其尺寸減至最小,以便为用于触摸板传感电极的PC板腾出空间。 In examining the prior art structure comprises a touchpad keyboard found plastic sheet is generally removed or made to minimize the size to make room for a touch panel sensing electrodes PC board. 这是图1中所示带有触摸板的情况。 This is the case with a touch panel shown in FIG. 在图2中,人类工程学键盘的较大尺寸允许在其中包括一个PC板而没有重大修改,但仍然要求为触摸板使用一个大的PC板。 In FIG. 2, human engineering keyboard including larger size allows a PC board without major changes, but still requires the use of a large touchpad PC board. 还必须穿过键盘壳体切开一个孔。 It must also pass through a hole cut the keyboard housing. 从而使触摸板表面暴露于指示对象。 Thereby indicating that the object is exposed to the surface of the touch panel. 除了包括一个PC板用于触摸板传感电极网格外,还必须包括某种装置用于把塑料薄片30、 36、 40上的导电迹线32、 38连接到控制电路。 In addition to including a PC board for the sensing electrode grid touchpad, but also must include some means for the plastic sheet 30, 36, 40 of the conductive traces 32, 38 is connected to the control circuit. 控制电路被^键盘壳体内的那些PC板上。 The control circuit is that the PC board in the keyboard housing ^. 由于所用材料的性质,这一连接器要比较强固。 Due to the nature of the material, to compare the strong connector. 例如,在导电迹线中使用的墨能氧化。 For example, the ink used in the conductive traces can be oxidized. 于是,使用的连接器,其施加较大的压力以迫使导电迹线压在PC板上的相应导电迹线,这一压力通常能克服氧化,但需要额外的硬件造成压力连接。 Thus, the use of connectors that large pressure is applied to force the conductive traces on the PC board pressure respective conductive traces, typically overcome this pressure oxidation, but it requires additional hardware caused by pressure connection. 如果提供一种装置减小装在键盘壳体内的触摸板所需PC板数量,那将是比现有技术优越。 If the touch panel is reduced to provide an apparatus mounted within the keyboard housing required number of the PC board, it would be superior to the prior art. 改善PC板和键盘塑料薄片之间的连接界面将是另一优点。 Improved connection interface between the PC board and the keyboard plastic sheet would be a further advantage. 利用塑料薄片用于触摸板的触摸板传感器电极,从而降低鍵盘的成本和复杂性,将是另一优点。 Using a plastic sheet for a touch panel sensor electrode of the touch panel, thereby reducing the cost and complexity of the keyboard will be another advantage. 另一个优点是提供一种新的方式把触摸板传感器电极安装到键盘壳体,与键盘本身的塑料薄片的存在无关。 Another advantage is to provide a new way to the touchpad sensor electrode is mounted to the keyboard housing, regardless of the presence of the keyboard plastic sheet itself. 最后,在柔性材料(如塑料或聚酯薄片)上提供触摸板传感器电极,从而使触摸板能符合于弯曲的表面,如键盘壳体的内部,这也是一个优点。 Finally, there is provided on the flexible material (such as plastic or a polyester sheet) touchpad sensor electrode, so that the touch panel can conform to a curved surface, such as the interior of the keyboard housing, which is an advantage. 发明内容本发明的一个目的是提供一种柔性表面,在其上放置触摸板传感器电极,从而使触摸板的表面能沿弧形表面放置。 SUMMARY An object of the present invention is to provide a flexible surface, is placed on the touchpad sensor electrodes thereon, so that the surface of the touch panel can be placed along the curved surface. 另一个目的是把触摸板和键盘集成到一个键盘壳体内,其中触摸板以键传感装置结构中使用的塑料薄片代替通常用于触摸板传感器电极的PC板材料。 Another object of the keyboard and the touchpad integrated into a keyboard housing, wherein the touch panel to bond the plastic sheet sensing device configuration used in place of PC board material commonly used for a touch panel sensor electrode. 另一个目的是改善PC板和用于触摸板传感器电极的塑料薄片之间的连接。 Another object is to improve the connection between the PC board and a plastic sheet for a touch panel sensor electrodes. 另一个目的是去掉压力连接器,以更可靠和成本较低的连接装置代8替它。 Another object is to remove the pressure connector, a more reliable and low cost generation of the connecting means 8 crispness. 另一个目的是通过使用用于键盘电路导电迹线的导电墨制造触摸板传感器电极来降低制造键盘的成本。 Another object of the conductive ink is a conductive electrode trace touchpad sensor manufactured by using a keyboard circuit to reduce the manufacturing costs of the keyboard. 另一个目的是通过使用具有高度制造偏差容限的触摸板电路使得能够以比较不精确的丝网印刷工艺制造传感器电极。 Another object is achieved by using a manufacturing variation touchpad circuitry height tolerances enables comparison imprecise screen printing process for fabricating a sensor electrode. 另一个目的是把传感器电极放置在塑料薄片上,然后把塑料薄片直接固定在键盘盖的下側,从而不需要在键盘盖中切孔以让用户接触触摸板。 Another object is to the sensor electrode is placed on the plastic sheet, the plastic sheet and then fixed directly to the lower side of the flip, so that no hole is cut in the flip to let the user contacts the touch panel. 在一个优选实施例中,本发明是一个触摸板,由用作触摸敏感表面的柔性不导电材料和在其上安装触摸板电路的PC板组合而成,其中通过产生由导电墨形成的导电迹线,把触摸板传感电极放置在触摸敏感表面上,该触摸敏感表面能符合各种弧形表面,并且能通过保护壳传感,从而使触摸敏感表面受到保护并且不与指示对象直接接触。 In a preferred embodiment, the present invention is a touch panel, a touch-sensitive surface serving as a flexible non-conductive material and a combination of the PC board touchpad circuitry mounted thereon, wherein a conductive ink is formed by creating conductive traces line, the touchpad sensing electrodes placed on the touch-sensitive surface, the touch-sensitive surface can meet a variety of curved surfaces, and by sensing the protective case, so that the touch-sensitive surface and protected from direct contact with the object indicated. 在本发明的第一方面中,触摸M置在具有多层塑料薄片的键盘内, 在这些薄片上放置用导电墨形成的导电迹线,其中触摸板传感器电极放在这些相同的塑料薄片上,但它们延伸到触摸板区域。 In a first aspect of the present invention, M is set in the touch keyboard having a multilayer plastic sheet, placing the conductive traces formed by conductive ink on the sheet, wherein the touchpad sensor electrodes on the same plastic sheet, they extend into the region of the touchpad. 在本发明的第二方面中, 一个新的连接器把塑料薄片的导电迹线与包括键盘或触摸板电路的至少一个PC板耦合,从而产生关于击键和触摸板控制的数据。 In a second aspect of the present invention, a new connector of the plastic sheet with conductive traces coupling the at least one PC board circuitry includes a keyboard or a touch pad, thereby producing keystroke data on the touch panel and controls. 在本发明的第三方面中,使用内在地具有低制造容限的低成本工艺(如丝网印刷(silkscreening))把触摸板传感电极置于塑料薄片上。 In a third aspect of the present invention, the use of inherently low manufacturing tolerances of low cost process (such as screen printing (silkscreening)) the touchpad sensor electrodes disposed on a plastic sheet. 在本发明的第四方面中,把触摸板传感电极放置在塑料薄片上的制造容限可以较低,因为驱动触摸板传感电极的电路在其设计中具有显著较高的动态范闺。 In a fourth aspect of the present invention, the sensing electrodes disposed on the touch panel plastic sheet manufacturing tolerances may be lower, because the drive circuit has a touch panel sensing electrodes significantly higher dynamic range Gui in their design. 在本发明的第五方面中,触摸板传感电极放置在塑料薄片上,这些塑料薄片又直接放置在键盘壳体的弧形顶盖的下側面上。 In a fifth aspect of the present invention, the sensing electrodes disposed on the touch panel a plastic

发明详述现在参考附图,图中对本发明的各部件给予数字表示,并用这些附图讨论本发明,从而使本领域技术人员能制作和使用本发明。 DETAILED DESCRIPTION Referring now to the drawings, FIG digital administered to each member representation of the present invention, and the present invention is discussed in these drawings so that those skilled in the art to make and use the invention. 应该理解, 下文的描述只是本发明原理的示例,不应看作是缩小了所附权利要求的范围。 It should be understood that the following description is only exemplary of the principles of the present invention and should not be seen as narrowing the scope of the appended claims. 本发明的这一优选实施例是一个触摸板,由用作触摸敏感表面的柔性非导电材料和在其上安装触摸板电路的PC板组合而成。 This preferred embodiment of the present invention is a touch panel, a touch-sensitive surface serving as a flexible non-conductive material and a touchpad circuitry mounted thereon a PC board combination. 使用不依赖于现有技术压力连接器的新的连接系统,使触摸敏感表面与装在PC板上的触摸板电路相连。 It is not dependent on the prior art a new connector system pressure connector is connected to the touch-sensitive surface of the touchpad circuitry mounted on the PC board. 10本发明的最有利方面之一是柔性触摸敏感表面。 One of the most advantageous aspects of the invention 10 is flexible touch sensitive surface. 这一方面是有利的, 因为该触摸敏感表面能符合于弧型表面。 This aspect is advantageous because the touch-sensitive surface can conform to curved surfaces. 例如, 一个人类工程学键盘往往有一个腕托。 For example, a ergonomic keyboard tend to have a wrist rest. 该腕托是在键下方的弯曲塑料表面。 The wrist rest is below the surface of the curved plastic key. 本发明能有利地放置在弯曲的腕托区下方而无需修改键盘壳体。 The present invention can advantageously be placed below the bent wrist rest area without modifying the keyboard housing. 这是因为本发明的触摸板也能通过非导电材料传感。 This is because the touch panel of the present invention is also non-conductive material by sensing. 这样,该触摸板在键盘壳体硬塑料之下得到保护并符合于壳体的弧形表面。 Thus, the touch pad is protected under the keyboard, hard plastic housing and conforming to the arcuate surface of the housing. 本发明的另一有利方面来自触摸传感电极在触摸敏感表面上的放置方式。 Another aspect of the present invention is advantageous from the touch sensing electrodes are placed in the touch-sensitive surface. 具体地说,导电迹线是由导电墨形成的。 Specifically, the conductive trace is formed from a conductive ink. 这是在许多现有技术键盘设计中用于产生导电迹线的同样的导电墨。 This is the same in many prior art conductive ink keyboard for generating conductive traces. 再有,尽管在塑料上用丝网印刷过程形成导电迹线会造成迹线间间距的变化,但这些是本发明的触摸板电路所容许的,因为其大的动态范围。 Further, although the conductive traces are formed by a screen printing process on a plastic may cause changes in pitch between tracks, but these are the touchpad circuitry according to the present invention allow, because of its large dynamic range. 包括内置触摸板的键盘的另一实施例能共用建造键盘键传感网格所用的制造工艺。 Built-in touch panel including a further embodiment of a keyboard construction of the manufacturing process can be shared keyboard sensor grid used. 在本发明中,键盘内触摸板的确切位置并不特别有关系。 In the present invention, the exact location of the touchpad keyboard is not particularly relevant. 重要的只是其上放置鍵盘键导电迹线的塑料薄片延着一个特定的方向延伸,从而使触摸板传感电极也能在其上放置。 Only important plastic sheet on which the keyboard is placed in the extension of the conductive traces extending a specific direction so that the touch pad sensor electrode can be placed thereon. 于是,触摸板能作为键盘所用塑料薄片的集成部件来制造。 Thus, the touch panel can be used as an integrated part of the keyboard is manufactured with plastic sheet. 于是,图4显示两个塑料薄片的透视图,这两个薄片以图3所示薄片同样的方式装配在一起,但在右边缘增加了一个较小空间用于触摸板传感电极。 Thus, FIG. 4 shows a perspective view of two plastic sheet, the two sheets in the same manner as the sheet shown in Figure 3 assembled together, but the right edge of a small increase in the space for a touch panel sensing electrodes. 应该看出,当触摸板传感电极保留的空间能在任何任意选择的位置,只要在键盘盖放在塑料薄片上时这一位置能方便地用作为触摸敏感表面所用空间即可。 It should be seen that, when the touch pad sensor electrode space can be retained at any position arbitrarily selected, as long as the flip in this position on the plastic sheet can be easily used as touch-sensitive surface to space. 这样,应该看出,可在任何方向制造触摸板传感电极所用塑料薄片的延伸部分。 Thus, it should be seen that a touch panel can be manufactured in any direction sensing electrode extends with a portion of the plastic sheet. 用于触摸板传感电极的塑料还能作为单独物件来制造,这也是本发明的一个方面。 Plastic A touchpad sensing electrodes can be manufactured as a separate item, which is also an aspect of the present invention. 使用便宜的丝网印刷工艺可认为是本发明的一个新的方面。 Inexpensive screen printing process can be considered as a new aspect of the present invention. 这一工艺在布置触摸板传感电极方面与使用PC板相比有其固有的不精确性。 This process of sensing electrodes disposed in the touch panel using the PC board has its inherent inaccuracy compared. 本发明的另一个新的方面是能够去掉塑料薄片的任何支持表面。 Another novel aspect of the present invention is the ability to remove any plastic sheet support surface. 这是通过把塑料薄片向上粘在键盘盖的底表面上实现的。 This plastic sheet is adhered by the upward on a bottom surface of the flip achieved. 这一设计有若干明显好处,首先是去掉了支持表面。 This design has several obvious advantages, the first is to remove the support surface. 另一个好处是如果在其中包括触摸板技术,则键盘制造商能选择突显在下面放置触摸板的区域,或者如果未包括触摸板则不突显该区域。 Another benefit is that if the touch pad technologies include, manufacturers can select the highlighted keyboard placed below the area of ​​the touchpad, the touchpad is not included or if the area is not highlighted. 对销售者而言好处是这两种情况能使用相同的键盘盖。 For sellers in terms of the benefits is that these two cases can use the same keyboard cover. 通常,在键盘壳体中使用触摸板必须在键盘顶盖中切孔,从而使用户能接触触摸板表面。 Typically, the touch panel must be cut hole in the keyboard in the keyboard housing in the cap, so that the user can contact with the touchpad surface. 然而,本发明能使用例如这样一种触摸板技术,这项技术被纳入到CIRQVE CORPORATION ( TM )的电容敏感触摸板中,在使用有平均厚度的键盘顶盖的情况下该触摸板仍将操作。 However, the present invention can be used, for example, a touch panel technology, which is incorporated into CIRQVE CORPORATION (TM) sensitive capacitive touch panel, the touch panel will operate without the use of an average thickness of the cap keyboard . 于是, 键盘顶盖较容易制造,因为不必为了触摸板表面而切孔或者使用带孔的模具造孔。 Thus, the keyboard cover easier to manufacture, since the cut surfaces do not have to touch panel using a die hole or perforated pore. 本发明的另一个新的方面是能够去掉压力连接器,该连接器是用于向塑料薄片及在其上安装触摸板控制电路的PC板施加压力。 Another novel aspect of the present invention is the ability to remove the pressure connector, the connector is for applying pressure to the plastic sheet and a touch panel PC board mounting thereon a control circuit. 图5A和5B 中显示典型的压力连接器,其中杆50用螺钉固定在至少一个塑料薄片52 和PC板54上,以使它们之间牢固的连接。 Shows a typical pressure connector of FIGS. 5A and 5B, the rod 50 which is screwed at least one plastic sheet 52 and the PC board 54, so that a firm connection therebetween. 以这种方式施加压力,从而使塑料薄片52和PC板54的表面56相遏之处有好的电接触。 In this manner pressure is applied to the plastic sheet 52 and the PC board 54 with surface 56 of the containment has a good electrical contact. 不利之处是需要螺钉58,以及固定这些螺钉的孔。 Disadvantage is the need to screw 58, and the fixing screw holes. 去掉压力连接器首先是由引进焊珠(solder bubble)实现的。 Pressure is removed from the first connector introduction bead (solder bubble) implementation. 最好是如闺6中所示在PC板62上产生焊珠60。 As is best shown in Figure 6 is generated Gui bead 60 on the PC board 62. 焊珠有利地产生一个区域,它使塑料薄片64弯曲,以在区域66中被固定到PC板62。 Advantageously produce a weld bead region, that the plastic sheet 64 is bent to be fixed in the region 66 to the PC board 62. 通过在PC板上的区域66中施用粘合剂,或在塑料薄片64上与PC板62接触的部分, 或者这二者上施用粘合剂,使塑料薄片64固定在PC板62上。 By administration of PC board 66 in the region of the binder, or part of the plastic sheet 64 in contact with the PC board 62, or both the application of the adhesive, the plastic sheet 64 fixed to the PC board 62. 如现在应该理解的那样,被提高的焊珠60使塑料薄片62在它与焊珠接触的地方施加更大的力,这只是因为塑料薄片被弯曲了。 As should now be appreciated, the bead 60 is increased so that the plastic sheet 62 where greater force is exerted in its contact with the bead, simply because of the plastic sheet is bent. 塑料薄片62的韧性足以能发生好的接触。 Plastic sheet 62 can occur good toughness sufficient contacting. 图7展示本发明的另一新特性,即焊珠的交错放置。 7 shows a further new feature of the present invention, FIG, i.e. bead interleaved. 在图6中区域66中的间距是可以看得见的,该间距为良好的连接产生所需要的张力, 与此同时,交错放置的另一目的在于这样能使PC板上的那些连接更靠近到一起。 Spacing zone 66 in FIG. 6 is visible, which is a good connection pitch produce the desired tension, at the same time, a further object of this is to allow interleaved those connections closer to the PC board together. 图7显示多个焊珠以交错图案放置。 Figure 7 shows a plurality of weld beads are placed in a staggered pattern. 图8说明把塑料薄片上的触摸板传感电极连接到PC板上导电迹线的另一种方法。 FIG 8 illustrates another method for the touch panel on the plastic sheet sensing electrodes connected to the conductive traces on the PC board. 例如,假定一个PC板被用作触摸板传感电极能依托的表面。 For example, assume that a PC board is used as the surface of the touch sensing electrodes can rely on the. 在一种情况中,触摸板传感电极放置在两个不同的塑料薄片上。 In one case, a touch panel sensing electrodes disposed on two different plastic sheet. 在第二种情况中, 一组触摸板传感电极在PC板上,而另一组在一个塑料薄片上。 In the second case, a set of electrodes on the touchpad sensor PC board, while the other set on a plastic sheet. 不论以哪种方式,都必须使触摸板传感电极与PC板上安装的控制电路接触。 Regardless of how they must touch panel control circuit and the sensor electrode in contact with the PC board is installed. 这如图8所示那样实现。 This is achieved as shown in Fig. PC板70被用作基片。 PC board 70 is used as the substrate. 焊料凸起(solder bump ) 72被置于PC板70上。 Solder bumps (solder bump) 72 is disposed on the PC board 70. 第一塑料薄片74放在该PC板上,在薄片中切出几个孔以给—出到达下方焊料凸起72的入口。 A first plastic sheet 74 placed on the PC board, the sheet is cut out to send several holes - the projections reach below the inlet 72 of the solder. 上面带有触摸板传感电极的第二塑料薄片76被放在与PC板70的焊料凸起72接触的位置。 The above second plastic sheet with the touch panel 76 is placed on the sensing electrode and the solder bump 70 contacts the PC board 72 position. 第一塑料薄片74的一部分被提高,而第二塑料薄片76的一部分被放在其下面。 Portion of the first plastic sheet 74 is increased, and the plastic portion of the second sheet 76 is placed below it. 然而,在第二塑料薄片76上的触摸板传感电极和焊料凸起72之间可能造成接触不充分。 However, the touch panel on the sensing electrode and the solder bump of the second plastic sheet 76 may result in insufficient contact between the 72. 为保证有好的电接触,第一塑料薄片74中的孔不是做在焊料凸起72的上方,而是代之以做在它们的前方。 To ensure good electrical contact, the first plastic sheet 74 is not made in the aperture 72 above the solder bump, but instead do the front thereof. 以这种方式, 第一塑料薄片74仍f焊料凸起72的上方,这样迫使第二塑料薄片76抵住焊料凸起72,如图9所示。 In this manner, the first plastic sheet 74 is still above the solder bump 72 f, thus forcing the second plastic sheet 76 against the solder bumps 72, as shown in FIG. 本发明的另一方面是,在这些不在PC板上放置触摸板传感电极的应用中,能使用比较便宜的PC板材料。 Another aspect of the present invention is applied touchpad sensing electrodes placed in a PC board which are not, it can be used relatively inexpensive PC board material. PC板的质量能显著影响最终产品的成本。 Quality PC board can significantly affect the cost of the final product. 在这种情况中,不需要为PC板使用高质量的材料,因为当使用CIRQUE CRPORATION ( TM)的触摸板控制电路时,触摸板传感电极不再需要这种高精度,从而使触摸板传感电极能被丝网印刷到塑料薄片上。 In this case, the need to use high quality materials for the PC board, because when used CIRQUE CRPORATION (TM) control circuit touchpad, the touchpad sensor electrodes are no longer required precision, so that the touch panel pass sense electrode can be screen printed onto the plastic sheet. 本发明的另一方面是能使塑料弯曲,从而使触摸敏感表面和有控制电路的PC板二者能装配到一个较小的空间。 Another aspect of the present invention is to make the plastic bending, so that both the touch-sensitive surface, and a control circuit of the PC board can be fitted into a smaller space. 例如,考虑如图10A中所示触摸板。 For example, consider the touch panel as shown in FIG 10A. 图10A是塑料薄片80的透视图,在薄片上放置触摸板传感电极。 10A is a perspective view of the plastic sheet 80 is placed on the touch pad sensor electrode sheet. 触摸板传感电极放在弯向PC板82的弯曲塑料薄片84上,PC板82被对齐从而放在触摸敏感表面塑料薄片80的下方。 Touch pad sensor electrode is bent in a curved plastic sheet 84 PC board 82, PC board 82 are aligned so that the plastic sheet is placed below the touch-sensitive surface 80. 塑料薄片80能固定在键盘壳体或单独的触摸板壳的下侧,而PC板则直接放在其下方。 Plastic sheet 80 can be fixed in a separate housing or a touch panel keyboard housing side, while the PC is placed directly below the plate. 这一结构安排的优点之一在于容纳触摸板所需整个空间减小了,因为不是把PC板放在一侧,而是直接把它放在触摸板表面的下方。 One of the advantages of this arrangement is that the structure of the entire space required for accommodating the touch panel is reduced because it is not on one side of the PC board, but it directly on the bottom surface of the touchpad. 只必须使触摸敏感表面与触摸板电路有适当的绝缘,从而使它们能放得比较靠近。 Only the touch-sensitive surface must have a suitable insulating touchpad circuitry so that they can be placed relatively close. 于是,当把PC板直接放在触摸敏感表面下方时单独的触摸板能更小。 Thus, when the PC board is placed directly beneath the touch-sensitive surface of the touch panel can separate smaller. 图IOB是图IOA的立面截面图,它显示触摸敏感表面塑料薄片80、 在下方的PC板82以及把触摸传感电极引到PC板的弯曲塑料薄片84。 FIG IOB is an elevational cross-sectional view of IOA, it displays a touch-sensitive surface of the plastic sheet 80, the bottom of the PC board 82 and the touch sensing electrode lead to the PC board 84 is bent plastic sheet. 图IOC是图IOA的顶视图,它显示触摸敏感表面塑料薄片80、弯曲塑料薄片84以及放在塑料薄片下方的PC板82的轮廓。 IOC is a top view of FIG IOA, which shows a touch sensitive surface contour the plastic sheet 80, the plastic sheet 84 and bending a plastic sheet on the bottom of the PC board 82. 应该理解,上面描迷的结构安排只是说明本发明原理的应用。 It should be understood that the above described structural arrangement is only illustrative of the application of the principles of the fans of the present invention. 本领域技术人员可以设计出多种修改和其他结构安排而不离开本发明的精神和范闺。 Those skilled in the art may devise various modifications and other structural arrangements without departing from the spirit and scope of the present invention Gui. 所附权利要求要涵盖这类^"改和结构安排。 To cover such ^ "modifications and structural arrangements of the appended claims.
